问题 By the end of 2018, more than______of the global population will be using a smart phone.
  
Nearly 2. 4 billion people around the world used a smart phone in 2017. By the end of 2018, more than a third of the global population will be using a smart phone.
   On the one hand, it sends us unlimited amounts of information. We don’t have to wait. Our devices ring, ping, vibrate and light up with the latest news from family, friends and around the world.
   On the other hand, this immediate access to information may become an addiction. And it may make some people feel lonely, anxious and depressed. These findings are from a 2018 study from San Francisco State University and have been published in Neuro Regulation.
   Erik Peper and Richard Harvey are both health education professors at the university. They led the study. In a statement to the press, the two professors claim that "overuse of smart phones is just like any other type of substance abuse. " Also, addiction to social media may affect our emotional state.
   The two professors asked 135 university students about their smart phone use and their feelings. They found that "students who used their phones the most reported higher levels of feeling . . . lonely, depressed and anxious. "
   But the researchers also suggest ways to fight back. They say that we can train our brains to be less addicted to our phones and computers. Erik Peper suggests turning off push notifications and other such alerts on our phones. More often than not, our devices share unimportant information as if our lives depended on it. Our brains see the notices the same way. And that is a problem. So, just turn them off.
   The researchers also suggest taking control of when and where you answer a text or email. You do not need to answer them all. And you certainly don’t need to answer them as soon as you get them.
   They also suggest setting limits on the time you spend on social media. If you want to catch up with friends on Facebook, set aside a small amount of time to it. Schedule periods of the day to focus on important tasks and do not allow technology to interfere.

选项 A、Health education professors Erik Peper and Richard Harvey, from San Francisco State University, led the study and have published their findings in Neuro Regulation.
B、The two professors Erik Peper and Richard Harvey asked 153 university students about their smart phone use and their feelings.
C、In a statement to the press, the two professors Erik Peper and Richard Harvey claim that "overuse of smart phones is just like any other type of substance abuse".
D、The immediate access to information in a smart phone may become an addiction, which may make some people feel lonely, anxious and depressed.

答案B

解析 特定信息的找寻和判断。A选项是对原文信息进行了整合,即“旧金山州立大学(San Francisco State University)的健康教育教授埃里克-佩珀(Erik Peper)和理查德-哈维(Richard Harvey)领导了这项研究,并将研究结果发表在《神经调节》(Neuro Regulation)杂志上”,由此可见A选项与原文信息一致。C选项表达的意思是“埃里克-佩珀(Erik Peper)和理查德-哈维(Richard Harvey)教授在给媒体的一份声明中表述,过度使用智能手机就像滥用其他类型的药物一样”,这与原文信息“the two professors claim that‘overuse of smart phones is just like any other type of substance abuse’”完全吻合。D选项可以从原文中找到相关论证, “On the other hand,this immediate access to information may become an addiction.And it may make some people feel lonely, anxious and depressed”,意思是“另一方面,这种即时获取信息的方式可能会让人上瘾。它可能会使一些人感到孤独、焦虑和沮丧”,由此可见此选项的表述是正确的。B选项与原文信息表述存在差异,原文中提到“The two professors asked 135 university students about their smart phone use and their feelings”,意思是“两位教授对135名大学生进行了调查,询问他们使用智能手机的情况和感受”,选项B将“135名大学生”换成“153名大学生”,很容易让学生忽略此数字信息的不一致,因此不正确的一项为B。
